Kris Allen wasn't trying to cause any trouble, he just wanted to share his love of music. Unfortunately, doing that at the Santa Monica pier requires some paperwork.

The American Idolwinner explains what exactly happened with the impromptu concert that got shut down by police on Sunday, by telling E! News, "The idea was wrong. I probably was doing something I shouldn't have. I didn't mean to disrespect anybody or break the law."

"I got kind of bored yesterday and wanted to play some music and let my fans hear some stuff," he told us. "I just wanted to set up and play some music. I didn't know the rules. I thought the rule was if I wasn't selling anything I could do it. I just wanted to go out and play."

Which is totally understandable, except this guy has a pretty big fanbase, so you can guess how many people showed up.

"The crowd kind of got progressively bigger and I was actually playing the last song and this cop comes up, and he has got to be biggest dude I have ever seen, and he is pissed at me, just so mad. He is like, 'Stop man, stop it—you're not supposed to be here.' I'm like, 'Sorry man, I didn't know.' I went to go shake his hand and he was like, 'I don't shake hands with anybody.'"

Ouch!

"I just wasn't supposed to be there," he continued. "I was causing more of a ruckus than they wanted. You are supposed to have a permit and I had no idea. Oops. Rock 'n' roll."

And Allen makes sure to clear up some miscommunication to his fans about the consequences he faced, "People thought I got arrested, but I didn't. I didn't even get a ticket. I think that guy [cop] was scared of me."
